Abstract
In this paper, we define a tempered space-time fractional negative binomial
process (TSTFNBP) by subordinating the fractional Poisson process with an
independent tempered Mittag-Leffler L\'{e}vy subordinator. We study its
distributional properties and its connection to partial differential equations.
We derive the asymptotic behavior of its fractional order moments and
long-range dependence property. It is shown that the TSTFNBP exhibits
overdispersion. We also obtain some results related to the first-passage time.
